Police arrested Cornish over the weekend and found 50 other signed applications after searching his apartment.

Investigators fear that there are more victims out there.

"They can come forward, because if they were afraid of him they don't have to be afraid of him," said Chitwood. "He's in jail now. We have a strong case against him. If there are other victims, they have to come forward."

Cornish is being held on $250,000 bail. He is charged with several offenses, including rape and human trafficking.

Anyone with information about this case, and any other possible victims, are urged to contact Upper Darby Police at 610-734-3439.
